Description

Technical Field

[0001] The present invention relates to a locking and unlocking system for controlling the locking and unlocking of an object to be locked.

Background Art

[0002] For example, in a locking and unlocking system using a so-called smart lock that controls the locking and unlocking of a door with a digital key, there is one that enables temporary unlocking of the door by using a so-called one-time password as shown in Patent Document 1. In such a system, the one-time password is transmitted from, for example, a key management cloud to a mobile terminal and used by a door unlocking device. If the one-time password has a short usable time, the risk of it leaking and being misused is reduced, and the security of the locking and unlocking system can be improved.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, if the one-time password is set to be usable only for a short time, a person trying to unlock the door will have to obtain the one-time password near the door. Obtaining the one-time password can be done, for example, simply by operating a mobile terminal. At first glance, it seems easy, but it is troublesome for a person whose hands are occupied, such as when their hands are full of luggage. For example, if a delivery person with their hands full of luggage tries to obtain the one-time password by operating a mobile terminal, they will have to put down the luggage in their hands once, which is a heavy burden.

[0005] Problems related to the convenience and security of such unlocking and locking systems are problems that can occur commonly in unlocking and locking systems other than door unlocking and locking systems.

[0006] Therefore, the present invention has been made to solve the above problems, and it is to provide an unlocking and locking system that can reduce the labor at the unlocking site and reduce the risk of unauthorized use of unlocking data.

Means for Solving the Problems

[0007] The present invention has the following configuration.

[0008] [1] An unlocking and locking system including an unlocking and locking control device that controls unlocking and locking of an object to be locked, and a portable terminal capable of communicating with the unlocking and locking control device, The portable terminal, has an unlocking data storage unit that stores unlocking data for unlocking an object to be locked, and an unlocking request unit that outputs the unlocking data stored in the unlocking data storage unit, The unlocking and locking control device receives the unlocking data output from the unlocking request unit, determines whether it is pre-registered, and has a lock control unit that outputs an unlocking command signal to the object to be locked when it is determined that it is pre-registered. The portable terminal further has a deletion unit that deletes the unlocking data from the unlocking data storage unit when it is determined that the unlocking data output from the unlocking request unit has been used for unlocking the object to be locked. The unlocking and locking system is characterized by this.

[0009] With such an unlocking and locking system configured in this way, by storing unlocking data in the portable terminal in advance, it is possible to eliminate the labor of obtaining the unlocking data at the portable terminal near the unlocking site, and since the used unlocking data is deleted from the portable terminal, the unlocking data does not continue to remain in the portable terminal, and for example, the risk of leakage and unauthorized use can be reduced. In addition, since the used unlocking data is deleted from the mobile terminal, it is not necessary to change or reset the unlocking data registered on the unlocking / locking control device side. As a result, the unlocking / locking system can be simplified.

[0010] [2] The deletion unit The unlocking / locking system according to [1], wherein when the lock control unit receives the unlocking data from the unlocking request unit, determines that the unlocking data is pre-registered, or outputs the unlocking command signal to the object to be locked, it is determined that the unlocking data has been used. With such a configuration, it is possible to receive feedback from the lock control unit and delete the unlocking data that is determined to have been used with higher accuracy.

[0011] [3] The unlocking / locking control device is provided at the site where the object to be locked is located, is configured to be directly communicable with the mobile terminal, further includes an unlocking completion signal transmission unit that outputs an unlocking completion signal indicating that the unlocking of the object to be locked has been completed, The deletion unit determines that the unlocking data has been used when it receives the unlocking completion signal from the unlocking completion signal transmission unit or when the communication between the mobile terminal and the unlocking / locking control device is disconnected, according to the unlocking / locking system described in [1] to [2]. With such a configuration, at the site where the object to be locked is located, the unlocking data can be directly transmitted from the mobile terminal to the unlocking / locking control device. Therefore, for example, even at a site without a network environment, it is possible to unlock the object to be locked. And it is also possible to delete the used unlocking data and reduce the risk of unauthorized use without depending on the network environment. In this case, even at a site where a conventional smart lock cannot be applied due to a poor network environment, a highly secure unlocking / locking system can be constructed.

[0012] [4] The object to be locked is a door, The unlocking and locking control device further includes a person detection sensor that detects a person present within a predetermined area of the door. The deletion unit determines that the unlocking data has been used when it is determined that the person detected by the person detection sensor has passed through the door, for the unlocking and locking system according to [1] to [3]. With such a configuration, when the door is opened and an actual passerby passes through (uses) the door, the unlocking data is deleted. Therefore, it is possible to prevent the unlocking data from being erroneously deleted when the passerby has not passed through the door.

[0013] [5] The deletion unit when the person detected within the predetermined area in the unlocked state of the door is no longer detected or has moved in the direction of passing through the door, for the unlocking and locking system according to [4], determines that the detected person has passed through the door. With such a configuration, since the unlocking data is deleted after sufficient information is obtained from the person detection sensor, it is possible to delete the unlocking data that is determined to have been actually used with higher accuracy.

[0014] [6] The deletion unit deletes the unlocking data from the unlocking data storage unit when it is determined that the unlocking data output from the unlocking request unit has been used a predetermined number of times for unlocking the object to be locked, for the unlocking and locking system according to any one of [1] to [5]. When it is desired to unlock the object to be locked multiple times, if the unlocking data is deleted after one use, it is necessary to obtain the unlocking data for that number of times, which is time-consuming. Therefore, with the configuration of [6], the unlocking data can be used a predetermined number of times, improving convenience. Although the risk of unauthorized use increases as the number of available uses increases, by appropriately setting the predetermined number of times, a balance between this convenience and security can be achieved.

[0015] [7] The unlocking data deletion unit deletes the unlocking data that has elapsed a predetermined period from the unlocking data storage unit since it was determined to be used for the first time or since it was determined to be used last, according to the unlocking and locking system described in any one of [1] to [5]. With such a configuration, the unlocking data can be used many times within a predetermined period from the first use, or the unlocking data can be continuously used as long as it is continuously used without an interval. This is convenient when the locked object must be unlocked many times within a certain period, for example, when a moving company needs to pass through an auto-lock door many times. If the predetermined period during which it can be used is long, the risk of unauthorized use also increases. However, by appropriately setting the predetermined period, a balance between this convenience and security can be achieved.

[0016] [8] The unlocking and locking system further includes a management server capable of communicating with the mobile terminal via a network. The management server further includes a server storage unit for storing unlocking data, and an unlocking permission granting unit for outputting the unlocking data stored in the server storage unit. The mobile terminal further has an unlocking permission acquisition unit that transmits user data for identifying the user carrying the mobile terminal to the unlocking permission granting unit, and stores the received unlocking data in the unlocking data storage unit when receiving the unlocking data from the unlocking permission granting unit. The unlocking permission granting unit determines whether the user data received from the unlocking permission acquisition unit is pre-registered, and transmits the unlocking data to the unlocking permission acquisition unit when it is determined that it is pre-registered, according to the unlocking and locking system described in [1] to [7]. With such a configuration, for example, the unlocking data can be given only to the registered mobile terminal, so the risk of unauthorized use of the unlocking data can be reduced.

[0017] [9] The unlocking and locking system according to [4] or [5], wherein communication between the mobile terminal and the unlocking and locking control device starts after the human detection sensor detects a person. With such a configuration, unlocking can be performed only when the user is actually near the door.

[0018]

[10] A delivery system including the unlocking and locking system according to [4], [5] or [9]. Delivery is mainly used for delivering luggage to a residence. In an apartment building or the like, when the delivery location is inside a locked door such as a shared entrance, the resident of the delivery destination who is away cannot unlock the door. On the other hand, if a smart lock system using a one-time password is introduced to the door of the delivery destination such as an apartment building, the delivery operator can obtain a one-time password for unlocking this lock by performing a predetermined operation on the mobile terminal. However, since the hands of the delivery operator are often blocked by the luggage to be delivered, if the delivery operator tries to operate the mobile terminal to obtain the one-time password, it is necessary to put down the luggage on the ground or release it once. Putting down the luggage once near the door every time of delivery is a great burden on the delivery operator, and there may be cases where the luggage cannot be put down on rainy days or the like. Regarding such a problem, with the configuration of

[10] , since the unlocking data for unlocking the door of the delivery destination is stored in the mobile terminal in advance, the delivery operator does not need to operate the mobile terminal to obtain the unlocking data at the delivery destination. For example, when the operator is holding luggage and both hands are blocked, the trouble of putting down the luggage once in front of the door can be reduced. In addition, since the used unlocking data is deleted, the unlocking data does not continue to remain in the mobile terminal 200 after the delivery is completed, and the risk of unauthorized use by the delivery operator outside of work or leakage of the unlocking data can also be reduced.

Advantages of the Invention

[0019] According to the present invention configured as described above, it is possible to provide a locking and unlocking system that can reduce the risk of unauthorized use of unlocking data while reducing the labor at the unlocking site.

Modes for Carrying Out the Invention

[0021] An embodiment of the locking and unlocking system according to the present invention will be described with reference to the drawings.

[0022] [First Embodiment] 1. System Overview The locking and unlocking system according to the first embodiment is provided at the common entrance of an apartment building (hereinafter also simply referred to as the entrance), such as a condominium, and is for unlocking an automatic door locked by an auto-lock or the like for temporary facility users (here, delivery workers). In this locking and unlocking system, delivery workers can obtain in advance the unlocking data necessary for unlocking the automatic door of the apartment building that is the delivery destination. In the present embodiment, the locked state of the automatic door indicates the closed state of the door, and the unlocked state indicates the open state of the door.

[0023] 2. System Configuration 2-1. Overall Configuration As shown in FIGS. 1 to 3, this unlocking and locking system is configured using a management server 100 that manages unlocking data for unlocking the automatic door D, a mobile terminal 200 carried by a delivery person, and an unlocking and locking control device 300 attached near the automatic door D and controlling the unlocking and locking of the automatic door D.

[0024] The unlocking data is a key necessary for the unlocking and locking control device 300 to unlock the automatic door D, and is, for example, a password preset in the unlocking and locking control device 300.

[0025] The management server 100 and the mobile terminal 200 can transmit and receive signals and data to and from each other via a network N such as the Internet or a telephone line, and the mobile terminal 200 and the unlocking and locking control device 300 can directly transmit and receive signals and data to and from each other via one-to-one local communication using, for example, BLE.

[0026] 2-2. Management Server 100 The management server 100 collectively manages the unlocking data of the unlocking and locking control devices 300 installed in a plurality of apartment buildings and the like. The management server 100 is a computer equipped with a CPU, a memory, a communication interface, etc., and is configured to be able to communicate with external devices via the network N etc. as shown in FIG. 1. Note that the management server 100 may be a virtual computer provided on the cloud.

[0027] The management server 100 functions as a server storage unit 11 and an unlocking authority granting unit 12 by the cooperation of the CPU and peripheral devices according to a predetermined program stored in the memory.

[0028] 2-2-1. Server Storage Unit 11 The server storage unit 11 is set in a predetermined area of the memory of the management server 100. As shown in FIG. 3, this server storage unit 11 creates a database by associating the property ID of a condominium or the like, the device ID of the locking / unlocking control device 300 installed in the condominium or the like, and the unlocking data of the locking / unlocking control device 300, and stores them.

[0029] In this property database, the property ID and the like are associated with the user ID of the delivery service provider permitted to use (here, delivery) the condominium indicated by the property ID.

[0030] 2-2-2. Unlocking Authority Granting Unit 12 The unlocking authority granting unit 12 refers to the property database, checks whether the delivery service provider is permitted to make a delivery in the condominium for which the delivery service provider requests unlocking, and if permitted, outputs the unlocking data of the locking / unlocking control device 300 installed in the condominium. The unlocking authority granting unit 12 of the present embodiment refers to the property database and outputs the unlocking data together with the device ID of the locking / unlocking control device 300 associated with the unlocking data.

[0031] 2-3. Mobile Terminal 200 The mobile terminal 200 includes a CPU, a memory, input / output devices such as a touch panel display, a communication interface, etc., and is, for example, a smartphone, a tablet, a personal computer, etc. As shown in FIG. 1, the mobile terminal 200 is configured to be able to communicate with external devices via the network N, Bluetooth (registered trademark) Low Energy (so-called BLE), etc. Note that the mobile terminal 200 may be a BLE tag equipped with a microcomputer.

[0032] The mobile terminal 200 functions as at least a user data storage unit 21, an unlocking authority acquisition unit 22, an unlocking data storage unit 23, and an unlocking request unit 24 by the cooperation of the CPU and peripheral devices according to a predetermined program stored in the memory.

[0033] 2-3-1. User Data Storage Unit 21 The user data storage unit 21 is set in a predetermined area of the memory of the mobile terminal 200. This user data storage unit 21 stores in advance user data (here, the user ID which is an identification number for each delivery agent) for identifying the user of the locking / unlocking system who carries the mobile terminal 200. The user ID is, for example, the business ID indicating the delivery company to which the delivery agent belongs, the employee ID of the delivery agent, or the like.

[0034] In this embodiment, the user ID is stored in the user data storage unit 21 as part of the baggage slip (waybill) data.

[0035] This slip data relates to the baggage handled by the delivery agent who holds the mobile terminal 200, and includes information indicating the contents of the baggage, information for specifying the delivery destination or the sender, information indicating the delivery conditions, etc. in a state where they are linked to each other. Here, it includes at least the property ID for identifying the apartment house or the like of the delivery destination.

[0036] As shown in FIG. 4, a slip database including the slip data of a plurality of pieces of baggage is stored in the user data storage unit 21 of this embodiment.

[0037] 2-3-2. Unlocking Authority Acquisition Unit 22 The unlocking authority acquisition unit 22 transmits the property ID and the user ID to the unlocking authority granting unit 12, and requests the granting of the unlocking data of the unlocking / locking control device 300 installed in the apartment house or the like indicated by the property ID. Note that the unlocking authority acquisition unit 22 only needs to transmit at least the information necessary for specifying the unlocking / locking control device 300 to the unlocking authority granting unit 12, and may transmit only the device ID, the user ID, or the like.

[0038] When the unlocking authority acquisition unit 22 receives the unlocking data from the unlocking authority granting unit 12, it stores the unlocking data in the unlocking data storage unit 23 described later. The unlocking authority acquisition unit 22 of this embodiment stores the unlocking data received from the unlocking authority granting unit 12 in the unlocking data storage unit 23 in association with the device ID.

[0039] The unlocking authority acquisition unit 22 of this embodiment is configured to be able to acquire unlocking data necessary for delivering the luggage assigned to the substitute delivery person by referring to the slip data stored in the user data storage unit 21.

[0040] The unlocking right acquisition unit may automatically refer to the slip data to acquire the unlocking data, or may acquire the unlocking data when the substitute delivery person performs a predetermined operation on the mobile terminal 200.

[0041] 2-3-3. Unlocking Data Storage Unit 23 The unlocking data storage unit 23 is set in a predetermined area of the memory of the mobile terminal 200. This unlocking data storage unit 23 stores the unlocking data in association with the device ID of the unlocking and locking control device 300 that the unlocking data unlocks and locks. The unlocking data storage unit 23 can store the unlocking data of a plurality of unlocking and locking control devices 300.

[0042] Note that as long as at least the substitute delivery person performs the operations required for normal business, the unlocking data stored in the unlocking data storage unit 23 is kept secret from the person operating the mobile terminal 200 and is configured not to be disclosed via, for example, a display or the like.

[0043] In this embodiment, the unlocking data stored in the unlocking data storage unit 23 is acquired from the management server, but the unlocking data storage unit 23 may store the unlocking data acquired by other means. For example, the unlocking data storage unit 23 may store in advance the unlocking data input from an input unit such as a touch panel of the mobile terminal or the unlocking data acquired from other devices via wired communication.

[0044] 2-3-3. Unlocking Request Unit 24 The unlocking request unit 24 outputs the unlocking data stored in the unlocking data storage unit 23 and requests the unlocking of the automatic door.

[0045] 2-4. Locking / Unlocking Control Device 300 As shown in FIGS. 1 to 3, the locking / unlocking control device 300 receives unlocking data from the mobile terminal 200 and controls the locking and unlocking of the automatic door D. It is provided near the automatic door D (here it is invisible) and includes an information processing device P.

[0046] Furthermore, the locking / unlocking control device 300 of the present embodiment further includes a human detection sensor for detecting a person who has entered a predetermined detection area AR. The locking / unlocking control device 300 of the present embodiment is a door sensor device that includes the information processing device P and the human detection sensor S in one housing. Note that the information processing device P and the human detection sensor S may be provided in different housings.

[0047] 2-4-1. Human Detection Sensor S As shown in FIG. 3 and the like, the human detection sensor S detects whether a person has entered the detection area AR set near the outside of the doorway area and outputs a detection signal indicating the same. Specifically, as this human detection sensor S, various types such as a passive infrared sensor, an active infrared sensor, a radar sensor using microwave or millimeter wave, or a camera sensor using an imaging device can be used.

[0048] 2-4-2. Information Processing Device P The information processing device P is a so-called computer equipped with a CPU, a memory, an I / O interface, a communication interface, etc., and is configured to be communicable with external devices via BLE or the like as shown in FIG. 1.

[0049] This information processing device P exhibits functions as a lock control unit 31 and an unlocking completion signal transmission unit 34 by the CPU and peripheral devices cooperating according to a predetermined program stored in the memory.

[0050] In the memory of the information processing apparatus P, a device ID for identifying the unlocking and locking control device 300 and unlocking data of the unlocking and locking control device 300 are stored in advance. Here, the unlocking data stored in the memory is registered in advance at the time of shipment or installation of the unlocking and locking control device 300. A plurality of such pre-registered unlocking data may be registered.

[0051] 2-4-3. Lock control unit 31 As shown in FIG. 3, the lock control unit 31 includes an unlocking data authentication unit 32 that authenticates the unlocking data, and an unlocking command signal transmission unit 33 that outputs an unlocking command signal to the opening / closing drive device D1 of the automatic door D based on the authentication result.

[0052] The unlocking data authentication unit 32 determines whether the unlocking data received from the unlocking request unit 24 is pre-registered. If it is determined that the unlocking data is pre-registered, it is determined that the authentication of the unlocking data has been successful. In the present embodiment, if the received unlocking data matches the unlocking data pre-stored in the memory of the information processing apparatus P, it is determined that the authentication has been successful.

[0053] The unlocking command signal transmission unit 33 outputs an unlocking command signal based on the authentication result of the unlocking data authentication unit 32. In the present embodiment, however, the unlocking command signal is output based not only on this authentication result but also on the detection signal output from the human detection sensor S.

[0054] That is, the lock control unit 31 of the present embodiment outputs an unlocking command signal when the unlocking data authentication unit 32 determines that the authentication has been successful and when the human detection sensor S detects a person.

[0055] 2-4-5. Unlocking completion signal transmission unit 34 The unlocking completion signal transmission unit 34 outputs an unlocking completion signal indicating that the unlocking of the automatic door D has been completed. Specifically, when the unlocking completion signal transmitting unit 34 receives a signal indicating that the door opening operation (unlocking operation) of the automatic door D has been completed from the opening / closing driving device D1 of the automatic door D, it determines that the unlocking of the automatic door D has been completed and outputs an unlocking completion signal.

[0056] 2-5. Deletion Unit 25 Thus, the mobile terminal of the present embodiment further functions as a deletion unit 25. When the deletion unit 25 determines that the unlocking data output from the unlocking request unit 24 has been used for unlocking the automatic door D, it deletes the unlocking data from the unlocking data storage unit 23.

[0057] When the deletion unit 25 of the present embodiment receives an unlocking completion signal from the unlocking completion signal transmitting unit 34 as a result of outputting unlocking data from the unlocking request unit 24, it determines that the unlocking data has been used and deletes this used unlocking data. Note that the deletion unit 25 may substantially delete the unlocking data that can be used for unlocking by modifying and invalidating the unlocking data in the unlocking data storage unit 23 or changing the status of the unlocking data to a unusable state. The deleted unlocking data may be erased so that it cannot be restored.

[0058] 3. System Operation 3-1. Pre-acquisition of Unlocking Data As shown in FIG. 3, when the delivery person operates the mobile terminal 200 to select one piece of luggage from the invoice database, the unlocking authority acquisition unit 22 transmits the property ID of the delivery destination associated with the luggage and the user ID of the delivery person to the unlocking authority granting unit 12 (step S1).

[0059] The unlocking authority granting unit 12 searches the property database and determines whether the delivery person indicated by the received user ID is permitted to make a delivery in the apartment building indicated by the received property ID (step S2).

[0060] If it is determined that placing is permitted, the unlocking data of the automatic door D of the apartment house is transmitted to the unlocking authority acquisition unit 22 together with the device ID of the locking / unlocking control device of the automatic door D (step S3).

[0061] The unlocking authority acquisition unit 22 associates the received unlocking data with the device ID and stores it in the unlocking data storage unit 23 (step S4).

[0062] Thus, the pre-acquisition of the unlocking data may be executed manually, or may be automatically executed for a package whose distance to the apartment house at the delivery destination or the like becomes equal to or less than a predetermined distance based on the position information such as GPS incorporated in the mobile terminal 200, for example.

[0063] Note that in step S2, the selected slip data may be transmitted to the unlocking authority granting unit 12.

[0064] 3-2. Unlocking of Automatic Door As shown in FIG. 4, when the delivery person arrives at the entrance of the apartment house at the delivery destination and enters the predetermined detection area AR, the human detection sensor S transmits a detection signal.

[0065] In a state where the information processing device P has received this detection signal (step S11), it transmits a beacon signal indicating the device ID of the locking / unlocking control device 300 to a predetermined reception range using BLE (step S12).

[0066] If the device ID indicated by the received beacon signal is stored in the storage unit, the mobile terminal 200 of the delivery person attempts local communication with the lock control unit 31 of the locking / unlocking control device 300 (step S13).

[0067] When the local communication is established, the unlocking request unit 24 specifies the one corresponding to the device ID indicated by the beacon signal from the unlocking data in the unlocking data storage unit 23 and transmits it to the unlocking data authentication unit 32 (steps S14 and S15).

[0068] The unlocking data authentication unit 32 determines whether the received unlocking data matches the pre-registered unlocking data, that is, whether the distributor has the unlocking authority (step S16).

[0069] When it is determined that the unlocking authority is available, if the unlocking command signal transmission unit 33 is in a state of receiving the detection signal from the human detection sensor S, the unlocking command signal transmission unit 33 transmits an unlocking command signal to the opening / closing drive device D1 (step S17) to unlock (open) the automatic door D.

[0070] 3-3. Deletion of Used Unlocking Data When the opening / closing drive device D1 opens the automatic door D, it transmits a signal indicating that to the unlocking completion signal transmission unit 34. The unlocking completion signal transmission unit 34 that has received this determines that the unlocking of the automatic door D is completed and transmits an unlocking completion signal to the deletion unit 25 (step S21).

[0071] The deletion unit 25 that has received the unlocking completion signal determines that the unlocking data was used for unlocking the automatic door D and deletes the used unlocking data from the unlocking data storage unit 23 (step S22). Note that the deletion unit 25 may delete the used unlocking data from the unlocking data storage unit 23 when the mobile terminal 200 that has received the unlocking completion signal disconnects the local communication with the unlocking / locking control device 300.

[0072] Note that the unlocking completion signal transmission unit 34 may determine that the unlocking of the automatic door D is completed and output an unlocking completion signal when the unlocking data authentication unit 32 receives unlocking data (step S15), when the authentication of the unlocking data is successful (step S16), or when the unlocking command signal transmission unit 33 outputs an unlocking command signal (step S17).

[0073] 4. Effects of the First Embodiment In the unlocking and locking system of the first embodiment configured as described above, since the unlocking data can be stored in the portable terminal 200 in advance, the delivery person does not need to operate the portable terminal 200 to acquire the unlocking data near the automatic door D, and for example, the trouble of putting down the luggage once in front of the door can be reduced.

[0074] Since the used unlocking data is deleted, the unlocking data does not continue to remain in the portable terminal 200 after the delivery is completed, and for example, the risk of leakage and unauthorized use is reduced.

[0075] Since the unlocking data stored in the portable terminal 200 is configured not to be disclosed to the person operating the portable terminal 200, while storing the unlocking data itself in the portable terminal 200, the risk of its leakage can be reduced.

[0076] Since the used unlocking data is deleted from the portable terminal 200, it is not necessary to change or re-set the unlocking data registered in advance in the unlocking and locking control device 300. Thereby, the unlocking and locking system can be simplified.

[0077] Based on the unlocking completion signal from the unlocking and locking control device 300, the unlocking data is deleted, so that the unlocking data determined to be used with higher accuracy can be deleted.

[0078] By the way, in the conventional smart lock system using a one-time password, for example, near the door, it is necessary to obtain the one-time password from the key management cloud to the portable terminal via the network, and it is difficult to apply to a site where the network environment near the door is unstable.

[0079] On the other hand, in the unlocking and locking system of the present embodiment, at the entrance of the apartment building where the automatic door D is arranged, the unlocking data can be directly transmitted from the mobile terminal 200 to the unlocking and locking control device 300. Therefore, for example, even at an entrance without (or unstable) network environment, the automatic door D can be stably unlocked. And without depending on the network environment, it is also possible to delete the used unlocking data to reduce the risk of unauthorized use.

[0080] Since the unlocking and locking control device 300 is configured to transmit a beacon after the human detection sensor S detects a person, unnecessary transmission of beacons to the surroundings can be reduced.

[0081] Since the automatic door D is unlocked based on both the human body detection by the human detection sensor S and the authentication of the unlocking data, it is possible to construct an unlocking and locking system for the automatic door D with higher security than when the door is unlocked and controlled by either one of them.

[0082] Since it is configured that the mobile terminal 200 can obtain the unlocking data when the authentication by the management server 100 is successful, the risk of unauthorized use of the unlocking data can be reduced.

[0083] The mobile terminal 200 of the first embodiment can use a general-purpose mobile terminal such as a smartphone, and the unlocking and locking control device 300 is configured as a door sensor device. With such a configuration, as a dedicated hardware, by simply preparing this door sensor device, the smart lock system according to the present invention can be introduced into the automatic door system. In addition, since it can be introduced regardless of the network environment at the entrance of an apartment building or the like, the labor and cost at the time of introduction can be suppressed.

[0084] [Second Embodiment] The unlocking completion signal transmission unit of the above embodiment outputs an unlocking completion signal when receiving a predetermined signal from the opening and closing drive device D1 of the automatic door D. In contrast, the unlocking completion signal transmission unit of the second embodiment outputs an unlocking completion signal based on a predetermined signal received from the opening / closing drive device D1 of the automatic door D and a detection signal received from the human detection sensor S.

[0085] Here, when a predetermined signal is received from the opening / closing drive device D1 and the person detected by the human detection sensor S within the detection area AR is no longer detected or has moved in the direction of passing through the doorway area, the unlocking completion signal transmission unit determines that the unlocking data has been used and that the person has passed through the automatic door, and outputs an unlocking completion signal.

[0086] In the unlocking and locking system configured in this way, since the unlocking and locking data is deleted after sufficient information is obtained from the detection sensor, the unlocking data that is actually determined to have been used with higher accuracy can be deleted.

[0087] [Third Embodiment] The deletion unit in each of the above embodiments deleted the unlocking data that had been used once. In contrast, the deletion unit of the third embodiment deletes the unlocking data from the unlocking data storage unit when it is determined that the unlocking data output from the unlocking request unit has been used a predetermined number of times for unlocking the automatic door.

[0088] Here, the deletion unit deletes a certain unlocking data when the number of times the unlocking completion signal has been received as a result of the output of the unlocking data from the unlocking request unit exceeds a predetermined number. The number of times the unlocking completion signal has been received is associated with the unlocking data and stored in the unlocking data storage unit.

[0089] In this case, the unlocking data can be used a predetermined number of times, improving convenience. Although the risk of unauthorized use increases as the number of available uses increases, this trade-off between convenience and security can be balanced by appropriately setting the predetermined number.

[0090] [Fourth Embodiment] The deletion unit according to the fourth embodiment deletes unlocking data from the unlocking data storage unit when a predetermined period has elapsed since the time when it was determined that the unlocking data was used for the first time or since the time when it was determined that the unlocking data was used last.

[0091] Here, for a certain piece of unlocking data, when a predetermined period has elapsed since the time when the unlocking completion signal was received for the first time as a result of the output of the unlocking data from the unlocking request unit or since the time when the unlocking completion signal was received last, the unlocking data is deleted. The time elapsed since the unlocking completion signal was received is associated with the unlocking data and stored in the unlocking data storage unit.

[0092] In this case, the unlocking data can be used multiple times within a predetermined period from the first use, or the unlocking data can be continuously used as long as it is used without an interval. This is convenient when the automatic door needs to be unlocked continuously multiple times within a certain period, for example, when a moving company needs to pass through an auto-lock door multiple times.

[0093] Although the risk of unauthorized use increases when the available period is long, this trade-off between convenience and security can be balanced by appropriately setting a predetermined period. [Other Embodiments]

[0094] The unlocking data may be transmitted and received in an encrypted state between the management server and the mobile terminal or between the mobile terminal and the unlocking / locking device. In this case, for example, the lock control unit determines whether the unlocking data received from the mobile terminal is pre-registered by checking whether the decrypted unlocking data matches the unlocking data pre-stored in the memory of the information processing device. In this case, for example, even if the communication between the mobile terminal and the unlocking / locking device is intercepted by a third party, the risk of the unlocking data leaking can be reduced.

[0095] The unlocking command signal transmission unit of each of the above embodiments outputs an unlocking command signal based on the authentication result of the unlocking data and the detection status of the human detection sensor. However, it may output an unlocking command signal based only on the authentication result of the unlocking data. The deletion unit of each of the above embodiments deletes the used unlocking data. However, the locking / unlocking system may delete the locking data for locking the automatic door after use.

[0096] The deletion unit may delete the unlocking data after a predetermined time has elapsed after the unlocking data is output from the unlocking request unit. In this case, since the unlocking data that may have been used can be deleted, the security can be improved. Also, if the predetermined period is too short, the unlocking data will be deleted immediately after output and cannot be reused. By adjusting the length of the predetermined period, convenience can be ensured. Also, when the local communication between the mobile terminal and the locking / unlocking device is disconnected, the deletion unit may delete the used unlocking data from the unlocking data storage unit 23 regardless of the unlocking status at that time. In this case, the unlocking data that may have been used can be deleted regardless of whether the unlocking was successful, and the security is improved.

[0097] When the unlocking data storage unit contains a plurality of mutually related unlocking data, and one of them is deleted as used unlocking data, the deletion unit may also delete the other related unlocking data together. In this case, it is convenient because the unlocking data associated with a plurality of packages with the same delivery destination, such as an apartment building, can be deleted all at once when these packages are delivered at once.

[0098] When the deletion unit deletes the unlocking data, information indicating that the unlocking data has been used (visited for delivery) may be added to the slip data referred to for acquiring the deleted unlocking data.

[0099] The unlocking and locking system of each of the above embodiments was composed of a management server, a mobile terminal, and an unlocking and locking control device. However, the physical configuration of the unlocking and locking system according to the present invention is not limited to this. For example, the unlocking and locking system may be composed of a mobile terminal and an unlocking and locking control device. The key point is that as long as it is an unlocking and locking system in which the unlocking data transmitted from the mobile terminal to the unlocking and locking control device and used for unlocking the object to be locked of the unlocking and locking control device is deleted from the mobile terminal.

[0100] The unlocking and locking control device may be configured to be communicable with external devices via a network N or the like. In this case, the unlocking and locking device may function as a locking control unit by remotely controlling the unlocking and locking of the object to be locked.

[0101] A signal indicating that the unlocking data has been deleted may be transmitted from the mobile terminal to the management server. In this way, on the management server side, the status of the granted unlocking data can be managed, and the security is improved.

[0102] Also, a deletion command signal for instructing the mobile terminal to delete the unlocking data stored in the unlocking data storage unit may be transmitted from the management server. In this way, the once-granted unlocking data can be deleted from the management server side according to changes in the situation or the like, and the security is improved.

[0103] The information processing device and the human detection sensor may be provided separately.

[0104] The unlocking and locking system of each of the above embodiments controlled the unlocking and locking of the automatic door as the object to be locked. However, it may control the unlocking and locking of a manual door, or may control the unlocking and locking of an object to be locked other than a door.

[0105] For example, the present invention may be applied to a locking and unlocking system that controls the locking and unlocking of a gate that restricts the movement of a vehicle, or may be applied to a car-sharing service or the like in which a vehicle is locked to persons other than the user. The present invention may be any locking and unlocking system in which used unlocking data used for unlocking a locking target is deleted from a mobile terminal.
